摘要 PURPOSE:To improve the visibility by storing a light emission unit which has a light source and a multiple layer of photoconductors formed by cutting conically the upper part of a column body made of a light-transmissive material in a globe. CONSTITUTION:The photoconductors 2 laminated above the light source 1 in layers are formed by cutting the upper parts of column bodies made of light transmissive materials in a conic shape 20 and the light emission unit A consists of the light source 1 and the photoconductors 2 in the layers and is held and stored in the globe 4 by chassis 3 and 3'. Therefore, light from the light source 1 is guided to the layers of the photoconductors 2, reflected by the conic cut parts, and scattered, so that the light is emitted out of the globe 4 in all directions. Consequently, the light is projected outward by the conductors with good visibility.
